Which Keilidh’s have you got? I’d guess the earlier ones with the mesh grille over the tweeter?
They're actually very late production examples (s/n: 54,7XX/54,7XX+1) with 015/3 tweeters, 013/4 woofers, and composite bases. The tweeters were damaged so I replaced them with good ones out of a pair of donor Tukans, checked to make sure the tweeter levels were set to factory default (they weren't) and let them play for about a month to allow the solder joints time to settle in, and to find the speakers' optimum position in the room.
There's still something unusual about this particular pair of Keilidhs. I've heard lots of Keilidhs, both aktiv and passiv, in lots of different rooms/systems over the years and they have all consistently sounded a bit dull/shut in (which is why I was a bit surprised to find the crossovers in this pair set to lower the tweeter output), but these sound quite lively and even a touch bright at times. It might be that my usual listening spot is higher and closer to the speakers than normal and the room is quite small, but their tonal balance is different than any other Keilidhs I've heard...in a good way! In this setup they sing the most musical tune I've heard from Keilidhs.
